Strongly recommend charuco #1515

There is a bug with our 8x8 chessboard that can result in bad calibration results with a small number of similar images. We should add a UI message that strongly recommends the charuco.

Is this a bug? Or is this not just a inherent property of calibration? If i take a small number of similar images of charuco, will this not happen?

It's inherent to mrcal+the opencv chessboard solver it seems? I'll dig up the old issue we had last year but it's specifically square chessboards
